It's a nice one Laurent. The dial in particular looks in great condition.

I'm a big fan of the second generation of Carrera, as this sample shows:

And I would agree that it does tend to be a little underrated sometimes. That makes it a good start for someone looking to own a Carrera, or indeed a first Heuer.

This one is row E-22 in our Carrera table, though that row could use a little adjustment now that we have a complete catalogue from 1972 rather than ones that focus on Cal 15 watches. The giveaway is the numbering of the hour register - showing each number from 1-12 was part of a general dial revision for all Heuer models that came in in 1972. The 1153 continued in this same configuration until replaced by the 110.253 in 1977, which was itself just a light reworking of the 1153 as its reference number suggests. So your watch is somewhere in that '72-77 period.

Here it is showing its face in that 1972 full catalogue:

The eagle eyed amongst you might spot that the catalogue watch has second execution hands, i.e. narrower than the hands on Laurent's watch. The fatter hands came shortly afterwards, better sized to relate to the double indices also introduced with the dial revision but it seems that some watches did actually make it to the wild with double indices and narrow hands, in this case it's not just a catalogue shot.

All in all a good buy Laurent, and doesn't it look good on the GF?!
